MACHINE FOR PUNCI-IING AND CUTTING TAPE.

App1ication filed. July 21,

Z '0 all whom it may concern:

Be it known that 1, JOHN A. M00111), a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky have invented a certain new and useful Improvement in Machines for Punching and Cutting Tape, of which My present invention pertains to an improved machine for facilitating the severance of a tape of paper or like material, preferably gummed or glued, into predetermined lengths, and for punching said tape so, as to produce so'called fish-tailed ends upon the tape when the same is severed.

The main object of the invention is to provide a simple machine wherein the previously gummed tape may be drawn off from a reel and severed into predetermined lengths (when such lengths are desired), and to punch the tape with suitably shaped openings across which the tape may be torn or severed to produce fish-tailed ends.

A further object is to provide a carriage for the punching mechanism, which carriage is adjustable toward or from the severing termined lengths may be formed.

lVith these and other objects in view, which will appear from the following description, reference will be made to the annexed drawings, wherein:

Referring to the drawings, 1 denotes a bottom plan View of-the punch;

suitable bed 01' table, upon which is secured a pair of L-shaped castings 2, see Figs. 3 and 5, said castings being arranged parallel to each other and extending lengthwise of the bed. At the rear end of the castings'is secured a bracket 3, which forms the support for an arm 1, which carries a reel 5 for the tape, denoted by 6. The tape passes from the reel beneath a roller- 7, forwardly throughthe punch press, in a manner to be presently described, thence beneath a roller 8, Fig. 2, through theforward guide 9, Fig. 15, and beneath the straight-edge orblade 10, against which the tape'isdrawn upwardlywhen' it is desiredto tear a section off. The blade 10 and guide 9 overlie a water-reservoir 11; and a roller 12, partly immersed in the water, standsimmediately adj acent the blade, the glued side of the tape (as the same is drawn forwardly). contacting with said roller.

To permit the operator to readily determine the length of strip withdrawn, prior to severance, an adjustable gage is provided. In the present instance it takes the form of a pin. or post 13, seeFigs. :1 to 1,.which ex- 7 clamped in its adjusted position through any Suitable means.

. The punching mechanism is likewise located along the supporting castings 2, and is designed to punch a diamond-shaped opening, as 15, in the tape, see Fig. 12. Secured to the opposite inner faces of the castings 2 are tracks or ways 16, Fig. 5, on which is slidably mounted a carriage 17 said carriage having an upwardly-extending column 18. Mounted upon the upper face of the carriage is a die-plate 19, having an opening therein of the size and shape corresponding to that which is to be punched in the ta e.

Mounted on the front face of the column 18, between guides 20 and 21, is a slide 22, the lower end of which (see Fig. 8) is re cessed to receive the rib 23 on the upper face of the punch or punching die 24, which is fixedly secured in place by a screw 25. The punch in outline conforms to the opening in the die-plate, and theunder face thereof is preferably slightly concave, see Fig. 10, so that the forward and rear points will first impinge upon the tape, whereby the tape is prevented from wrinkling and the cut partakes of the nature of a shearing cut from each end of the center.

To hold the tape closely to the underlying die-plate 19, a presser-plate 26 is employed. Said plate is provided with an opening through which the punch may pass and two posts 27 are threaded into the upper face the'reof,-said posts passing freely through openings formed in a cross-bar 28, fixed to slide -22. Nuts 29 are mounted on the upper ends of said posts, and springs 30 surround the posts, hearing at their opposite ends against the cross-bar and pressed-plate, and serving to force the plate-26 downwardly.

When the die'is elevated (see Fig. 6) the die and presser-plate stand above and free of the tape; when, however, the slide 22 is forced downwardly, plate 26. first clamps the tape against the underlying die-plate and comes to rest and the punch continuing its downward movement passes into the die-plate and punches out the tape, as shown in Fig. 12.

Preferably a power mechanism is employed to actuate the punch, said mechanism being under the direct control of the operator. 7

Secured to column 18 is a bracket 31 (Fig. 5) to which is pivoted a lever 32, said lever being secured to slide 22 by an arm 33. To the outer end of lever 32 is secured a link 34, the lower end whereof is pivotally connected to the outer end of a short lever 35, having a squared opening therein, through which extends a squared shaft 36. Lever 35 is adapted to slide on shaft 36, and is movable lengthwise thereof with the punch carriage 17. To effect this sliding movement a bracket 37 is se ured to the carriage and fingers 38 (Figs. 1 and 5) straddle said lever 35 and shift the same along the shaft in consonance with the carriage, as it is adjusted from one position to another. Shaft 36 is sustained alongside one of the members 2 in suitable bearings 39, 40, and to the rear end thereof is secured a rocker-arm 41, see Figs. 13 and 14. The outer end of the rockerarm is, pivotally connected to the upper end of a link 42, while the lower end of the link is pin-jointed to an eccentric strap 43, which surrounds an eccentric 44 loose upon the constantly-driven power-shaft 45-. A hub-shaped member 46 is secured to or formed integral with the eccentric and is provided with clutch teeth at its inner end. The hub is provided with an annular groove in which is wound a flexible cord 47, one end of the cord being attached to the frame of the machine, while the other i secured to one end of a coiled spring 48, said spring in turn being secured to the frame, see Fig. 1. This arrangement tends to draw the hub and its allied parts inwardly toward the toothed clutch element or hub 49, which is fast to the shaft. The clutch elements are designed to be normally held out of engagement and to be brought into operative relat-ion only when it is desired that the punch shall perforate the tape. hub 46 is provided with a cam face 50, and a lever 51, fulcrumed at 52, overlies the hub and is adapted (see Fig. 14) to coact with the cam face 50 and to shift the hub 46 laterally against the action of the spring drawn or tensioned belt or cord 47, thus separating the clutch elements. A spring 54 (Fig. 4) connected to the lower end of a link 55 which is also connected to the free end of lever 51, normally holds said lever against the cam face 50 and keeps the clutch elements out of engagement. The upper end of link 55 is connected to one arm of a bell-crank lever 56 and a draw-rod 57 is connected to the other arm, said rod extending forwardly and being connected at its forward end to one arm of a second bell-crank lever 58. A link 59, connected to the other arm of said lever, extends upwardly through an opening in the table '1 (see Fig. 15), its upper end being curved or made hook-shaped and overlying one end of a control lever 60. Said lever is fulcrumed upon a fixed bracket-shaped support 61 rising from the bed or table 1. A hookshaped limiting stop 62 is secured to said support 61 and stands over the upper end of link 59, so that the lever cannot be depressed too far.

With the parts in the positions shown in Figs. 1 and 2, lever 51 is held depressed and the clutch elements are separated; when, however, lever 60 is depressed link 59 is drawn upwardly and through bell crank 58,

To this end the rod 5 4, and bell-crank 56, link 55 is drawn upwardly against thetension of spring 54, and lever 51 is raised, withdrawing the same from engagement with cam face 50 and permitting spring 4:8 to tighten cord 47 and draw the clutch elements into engagement. The eccentric then partakes of the rotary motion of the driving shaft 45, link 42 being raised from the position shown in Fig. 13 to that in Fig. 14, thereby partially rotating shaft 36 and through lever 35, link 34:, lever 32 and arm 33, forcing slide 22 downwardly, causing the punch 24, carried thereby to pass through the underlying tape, as shown in Fig. 7

Upon the completion of the revolution of the eccentric, the parts will again come to their normal inactive positions, with the lever 51 bearing upon the cam face 50 and separating the clutch elements. This, of course, presupposes that the operator releases the lever 60 pressed, as it is only necessary that it should be moved down once to effect the punching operation for each opening formed in the tape.

The die-punching mechanism may, of course, remain inoperative, where straightend strips of tape are to be torn off or severed. When, however, fish-tail ends are to be produced, the operator will adjust the punch carriage along its ways a distance from the blade 10 equal to the desired length of strip to be severed, the tape being drawn forwardly until the widest portion of the opening 15 alines with the blade, at which time the operator will depress lever 60 and likewise draw against the blade 10. If desired, gage-pin or post 13 may be set away from the blade a distance equal to the desired length of strip, which distance, of course, will be equal to that of the distance between said blade and the center of the punch 24, thus enabling the operator to draw the tape outwardly and sever the same without the necessity of watching to see that the opening 15 therein properly registers with' the severing blade.

With a machine as above set forth it has been found that an operator may readily and with rapidity withdraw the tape and sever the same and apply such moistened, severed strips to boxes, packages,

Having thus described my invention, what I claim is: a
